  • LED optical energy detection and feedback system
    Patent number: 7045974
    Abstract: A system for the throughput detection and feedback of optical energy for making sure of white balance of the LED array in a flat fluorescent light source when the LED array in emitting light by respectively connecting in series a selected LED lamp respectively from RGB LED groups in an LED array to an optical energy sensor to convert optical energy into equivalent amperage, then voltage analog signals to digital signals for a CPU to compare and solve the difference of optical energy to improve voltage output, which then regulated by a driver and fed back to the LED array.
    Type: Grant

  • Cold cathode-ray tube driving method
    Publication number: 20030178952
    Abstract: A cold cathode-ray tube driving method by using a voltage with fixed phase shift to drive each cold cathode-ray tube of a backlighting module in a large size LCD; a circuit with phase excursion formed by the voltage so to provide a fixed phase shift between abutted loads to supply a highly consistent power source and to effectively control electricity leakage due to unstable phase shift between abutted loads.
